“…Elements grouped as major elements were those having an average concentration of >1 mg/kg in food products. 37 In agreement with previous studies, 23,24,38 K was the most abundant chemical element in Chinese honeys ( Table 2). In the honey samples tested, the highest K contents were found in the jujube honey samples, followed by the vitex, acacia, and rape honey samples.…”

The objective of this study is to test the feasibility of multi-isotopic and elemental analyses combined with chemometric techniques for differentiating the botanical origins of major honey products in China. The stable isotope and elemental compositions of 57 honey samples from four major floral origins in China (i.e., rape honey, acacia honey, vitex honey, and jujube honey) were analyzed using stable isotope ratio mass spectrometry (IRMS) and inductively coupled plasma mass spectrometry (ICP-MS), respectively. The results showed that hydrogen and oxygen isotopes could be more suitable than the carbon isotope for discriminating the floral origins of major honeys in China. There were significant differences in the contents of most elements between or among different floral origins. The combination of IRMS and ICP-MS methods provides the most effective and accurate approach (in most cases close to 100% accuracy) for classifying Chinese honeys according to their floral origins.

“…While elements such as cobalt, copper, chromium and nickel are essential components of biological structures, they can also be toxic at concentrations beyond functional limits. Other elements such as arsenic, lead, cadmium, magnesium and calcium are known for their toxic role in certain biochemical reactions [9,10]. In studies examining implants [11] and dental applications [12,13] in animals, AH Plus has been found to have biocompatible properties, but the effects of Obtuseal remain unknown.…”

Following root canal treatment, sealers may contact periapical tissue. The purpose of this study was to evaluate the systemic toxic effects of epoxy resin-based sealers (AH Plus and Obtuseal). Inductively coupled plasma-mass spectrometry (ICP-MS) was used to measure levels of trace elements (beryllium, magnesium, aluminium, calcium, chromium, arsenic and lead) in the brain, kidney and liver of rats. Twenty sterilized polyethylene tubes were then filled with AH Plus and Obtuseal and implanted into the dorsal subcutaneous tissue of 10 rats; three unoperated animals were used as a control group. After 45 days, the rats were sacrificed by cervical dislocation following anaesthesia, and brains, kidneys and livers were removed from all experimental animals. ICP-MS analysis was used to determine levels of trace elements. Data were analysed using KruskalWallis and Connover post hoc tests. No significant differences were found in aluminium and calcium levels, but brains, kidneys and livers showed significantly higher amounts of magnesium and chromium than the corresponding controls. In the kidney and liver samples, arsenic levels were found to be higher than in the control group. Lead was detected at higher levels only in liver samples from the AH Plus group. Beryllium was not detected in any organ. It was concluded that AH Plus and Obtuseal release minimal quantities of trace elements when in contact with subcutaneous tissue, and further studies are needed to understand the systemic effects of these materials.

“…The values of LOD were in the range of 0.4-8.0 (µg L -1 ) and the LOQ were 1.3-26 (µg L -1 ) ( Table 3). Precision was obtained as percent coefficient of variation (CV%) from the relative standard deviation of 10 repeated determinations of one sample [6]. The percent coefficients of variation (CV%) obtained for all trace elements were below 5.80%, ranging from 2.50 to 5.80% (Table 3).…”
